WTF Chevrolet engineers!
Yesterday I finally installed a set of headers and exhaust on my 2018 1LE. When I dropped the exhaust and got a good look at the crimp Chevrolet put in our exhaust system I was quite dismayed. How many ponies does this exhaust restriction cost us Camaro owners? Come on guys! You can do better.

FWIW - this has been covered several times on the forum and the evidence provided is that while the crimps look very restrictive there is no appreciable loss of power.

OP - FYI the crimp is there due to a subframe member on the convertible. But it's been covered many times before.

I would love to see the evidence. Has anybody actually done back to back testing of a car with the crimps and then with only the crimps eliminated? Apparently this has been covered, but this is my first time seeing how squeezed the exhaust pipe is at the muffler.

Sorry guys - no new revelations here. For peace of mind change it out if you wish but don't expect any meaningful performance boost.

Guaranteed to gain 20hp with the substitution of a normal straight, round pipe.*
